After the conflict ended, Halcrow's attention was soon focused upon various schemes in Scotland. For the
North of Scotland Hydro-Electric Board, a new generation of hydroelectric schemes to generate power for public consumption was developed. The
Glen Affric scheme, started in 1947, was the biggest of these; however, there were similar projects in neighbouring catchments, such as
Glen Garry and
Glen Moriston – the latter including one of the first
underground power stations in the UK – and Strathfarrar and Kilmorack.
In Wales, Halcrow's largest works were typically related to water supply schemes, such as the
Claerwen dam (completed in 1952) and the
Clywedog dam (completed in 1967), which created reservoirs that controlled the water levels of various rivers as well as reliably supplying various towns and cities across the
West Midlands. Halcrow also designed several railway tunnels, such as the
Woodhead Tunnel (completed in 1954) and at

The firm had several names during the 20th century, including CS Meik and
Buchanan (1920), CS Meik and Halcrow (1923), WT Halcrow and Partners (1941), Sir William Halcrow and Partners (1944), and, finally, Halcrow Group (1998).
21st century
By 2000, Halcrow Group's British-based projects accounted for roughly 60 percent of the company's turnover, while the remainder was derived from its undertakings outside of the British Isles.
By this point, the firm's consultancy work included a wide array of water, transportation, maritime, environment, power and property projects. Its customers included government departments, public sector authorities and utilities, industrial and commercial companies, international funding agencies and financial institutions.
During 2008, the company reported a turnover of £468 million; by this point, projects undertaken outside the UK accounted for 48% of total turnover.
It was long owned and managed by its employees and staff shareholders, Halcrow was operated as an independent concern up until late 2011.
CH2M
During September 2011,
CH2M Hill announced it was set to acquire the company,
and on 10 November 2011 CH2M Hill announced that it had completed the acquisition of Halcrow in exchange for £124m.
It was subsequently reported that Halcrow was effectively rescued by CH2M Hill, having incurred a pre-tax loss of £71m in its last year of independent trading (to 31 December 2011), on a turnover of £238m, down from £331m in 2010. Accounts lodged with
